1) 50 litres of a gas at 0 degrees celsuis are heated to 127degrees celsuis. What is the final volume? The pressure remains constant.
2) Calculate the density of CO2 gas at STP (in g/l)3) A cylinder in a gasole engine initially has a volume of0.50L and contains gases that exert a pressure of 101.3 kPa. What is the pressure of the gases when the volume of the cylinder is reduce to 0.20L and there is no change in the amount or temperature of the gaseous mixture?
